Synthesis and Characterization of Transition Metal Dichalcogenide Nanoribbons Based on a Controllable O₂ Etching.

ABSTRACT: Although the synthesis of monolayer transition metal dichalcogenides has been established in the last decade, synthesizing nanoribbons remains challenging. In this study, we have developed a straightforward method to obtain nanoribbons with controllable widths (25-8000 nm) and lengths (1-50 μm) by O₂ etching of the metallic phase in metallic/semiconducting in-plane heterostructures of monolayer MoS₂. We also successfully applied this process for synthesizing WS₂, MoSe₂, and WSe₂ nanoribbons. Furthermore, field-effect transistors of the nanoribbons show an on/off ratio of larger than 1000, photoresponses of 1000%, and time responses of 5 s. The nanoribbons were compared with monolayer MoS₂, highlighting a substantial differen
